    Pool opening after draining half the pool in winter

    Hey all, in short I had a post on here a couple months back where my under cover pump died, used siphon hoses to drain while ordering a new pump, forgot to remove one siphon hose, drained half of pool in the process since cover was on and I didnt see it, heavy rains then floated my liner, bad mess. Pool is full again now, liner sat back in place, and they are opening it today. Its a 28,000 gal inground SWG. It was drained to the point of about 2 inches deep in the shallow end, then filled back up with fresh water. So I know my water is in major need of everything.

    Just wondering what I should do first. Test all levels then add everything needed at once? Shock first? Add salt? I know the salt and chlorine levels will be way off, probably everything with be. I do have a drop test kit recommended by everyone here. I have been reading pool school, just want to go through the right steps since I had a rough winter with this thing.

    Is there a good way to test the salt levels, other than taking to pool store? Or just turn on the SWG and let it tell me?

    Just follow the steps here: pool-school/temporary_pool_guide

    Get the water balanced using bleach and all the rest. If the standing water is greenish, you'll need to perform the shock process. Instructions are in pool school. Otherwise, once it's balanced, then add the salt. You can buy salt test strips from or maybe at the local pool store. I'd recommend seeing where your salt level is before you start dumping bags in.

    Also note, a lot of SWG don't work when the water is cold, so there may be no reason to hurry. Do you have kids? If so, check out where-do-you-put-the-salt-skimmer-or-pool-t47475.html

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
